Hyperphosphatemia is an electrolyte disorder in which there is an elevated level of phosphate in the blood. [1] Most people have no symptoms while others develop calcium deposits in the soft tissue. [ 1 ]
Hyperphosphatemia causes acute kidney injury in tumor lysis syndrome, because of deposition of calcium phosphate crystals in the kidney parenchyma. [2] Hypocalcemia. Because of the hyperphosphatemia, calcium is precipitated to form calcium phosphate, leading to hypocalcemia. [2] Symptoms of hypocalcemia include (but are not limited to): [9] tetany
Laboratory evaluation reveal normal serum calcium levels and hyperphosphatemia. Rarely ALP (alkaline phosphatase – an enzyme active at sites of bone formation) may be elevated. Treatment is normalization of serum phosphate levels and resection of lesions. Surgical removal should be complete and if part of it is left, recurrence is likely to ...
Inherited hypoparathyroidism is rare and is due to a mutation in the calcium sensing receptor. Pseudohypoparathyroidism is maternally inherited and is categorized by hypocalcemia and hyperphosphatemia. Finally, pseudo-pseudohypoparathyroidism is paternally inherited.
Ectopic calcification is a pathologic deposition of calcium salts in tissues or bone growth in soft tissues.This can be a symptom of hyperphosphatemia.Formation of osseous tissue in soft tissues such as the lungs, eyes, arteries, or other organs is known as ectopic calcification, dystrophic calcification, or ectopic ossification.
Atherosclerosis: Overview. This article was reviewed by Craig Primack, MD, FACP, FAAP, FOMA. Atherosclerosis happens when a fatty substance called plaque builds up inside your arteries.
If the underlying cause of the hypocalcemia can be addressed, the hyperparathyroidism will resolve. In people with chronic kidney failure, treatment consists of dietary restriction of phosphorus; supplements containing an active form of vitamin D, such as calcitriol, doxercalciferol, paricalcitol; and phosphate binders, which are either calcium-based and non-calcium based.
There have been limited trials comparing phosphate binders to placebo in the treatment of hyperphosphatemia in people with chronic kidney disease. When compared with people receiving calcium-based binders, people taking sevelamer have a reduced all-cause mortality. [4]
